Answer:
One
Explanation:
Line A equation: y = -9x + 17
Line B equation: y = 3x + 5
Equal them.
-9x + 17 = 3x + 5
Add 9 to both sides.
17 = 12x + 5
Subtract 5 to both sides.
12 = 12x
Divide 12 to both sides.
x = 1
That means there is only one solution and when you input the 1 to the x to both equations you will get an answer like this 8 = 8. This means it's right and their equal for that one solution.
